Spring Security Essentials

By: Nanda Nachimuthu

Overview of this book

<p>Spring Security is a framework that focuses on providing both authentication and authorization to Java applications. Like all Spring projects, the real power of Spring Security is how easily it can be extended to meet custom requirements. The popularity of the Spring framework is increasing and the security package of Spring addresses vast mechanisms of Security in a rich way. Due to an increasing number of applications for various business needs, the integration of multiple applications is becoming inevitable. The standard security procedures available across multiple implementations in Spring will protect vulnerable applications that are open to larger public and private audiences.</p> <p>Spring Security Essentials focuses on the need to master the security layer, which is an area not often explored by a Spring developer.</p> <p>At the beginning, we’ll introduce various industry standard security mechanisms and the practical ways to integrate with them. We will also teach you about some up-to-date use cases such as building a security layer for RESTful web services and applications.</p> <p>The IDEs used and security servers involved are briefly explained, including the steps to install them. Many sample projects are also provided to help you practice your newly developed skills. Step-by-step instructions will help you master the security layer integration with the Server, then implement the experience gained from this book in your own real-time application.</p>

AOP basics


AOP is designed to handle modularization of concerns at source code level, which is called concerns. The concerns play a major role in AOP as this is used by multiple programs to address a specific reusable requirement; therefore, they are called cross-cutting concerns or horizontal concerns. In larger projects, a single line of code change may lead to many dependencies and impact the entire software development life cycle by undergoing processes such as code check-in, build, and testing. To make it easier, reducing the dependencies of larger code is important. AOP provides a solution to separate business code and cross-cutting concerns so that simple code changes do not affect the business functionality or behavior of the software bundle.

AOP creates a big impact on simplifying the system-level coding by implementing cross-cutting concerns. We can address each aspect separately in a modular fashion without tightly coupling the business logic and concerns. Avoiding duplication...
